Cap: 16-31 mm in diameter, convex to subcampanulate, with slight umbo, hygrophanous, darker at center of cap, fading to pale ochraceous buff to brownish-yellow and blue tinges are evident along the margin.

Gills:Adnate, with a yellow or dark olivaceous color, becoming purple-brown with age.

Stem:45-110 x 2-3 mm, equal and cylindrical, bulbous at the base. Intense bluing in stem after handling.

Spores:(10-) 12-14 (-16) x (5.5) 6.7-7 (-7.7) x 6.7µ.

Sporeprint: Chocolate to purple-brown.

Habitat: Gregarious on humus with woody or leafy debris, on trails and roadsides in Pinus radiata plantations in temperate and subtropical rainforests.

Distribution: Currently known only from South Australia.

Fruiting in April and May.

Dosage:   One or two large fresh mushrooms or one dried gram

Comment: Very close to Psilocybe subaeruginosa, Psilocybe aucklandii, Psilocybe eucalypta and Psilocybe tasmainiana. Several of these Australian, Tasmanian and New Zealand species noted above are closely aligned and related microscopically with Psilocybe azurescens, Psilocybe allenii and Psilocybe cyanescens from the Pacific Northwestern United States.
